What traditional uses of Tanseyleaf Aster have been recorded?
Tanseyleaf Aster was documented in several Native American traditions, with each use tied to a specific group and purpose. The Hopi used it for parturient women and as a stimulant, the Navajo for stomachache and nasal congestion, and the Zuni in flower infusions for unspecified illnesses. Each of these records comes from 20th-century ethnobotanical studies.
What did the Hopi record about Tanseyleaf Aster?
Among the Hopi, a decoction of the plant was taken by parturient women for any disorder, and another decoction was used as a strong stimulant. These uses were documented by Whiting in 1939 (Whiting, Alfred F., 1939, Ethnobotany of the Hopi, Museum of Northern Arizona Bulletin #15, page 31, 36, 94). The records do not specify preparation details or quantities.

How did the Navajo use Tanseyleaf Aster?
The Ramah Navajo recorded two uses: a decoction of the whole plant for stomachache, and the dried root used as snuff to cause sneezing for relief of a congested nose. Both uses were documented by Vestal in 1952 (Vestal, Paul A., 1952, The Ethnobotany of the Ramah Navaho, Papers of the Peabody Museum of American Archaeology and Ethnology 40(4):1-94, page 49).
What did the Zuni record about Tanseyleaf Aster?
Zuni tradition included an infusion of the flowers, taken with other flowers for unspecified illnesses. This use was recorded by Camazine and Bye in 1980 (Camazine, Scott and Robert A. Bye, 1980, A Study Of The Medical Ethnobotany Of The Zuni Indians of New Mexico, Journal of Ethnopharmacology 2:365-388, page 375). The details of the illnesses and the preparation were not specified.

Who should grow Tanseyleaf Aster and who should skip it?
Gardeners looking for a moderately drought-tolerant wildflower with a history in Southwestern landscapes may find Tanseyleaf Aster a good fit. It is not recorded as edible or palatable to humans, so skip it if you want a food crop. Households with pets do not face a recorded toxicity risk, but it is not a forage plant.
What are the trade-offs of growing Tanseyleaf Aster?
This plant handles moderate water and adapts to native soils, but it is not a showy perennial for every garden. Flowers are small and the plant can look weedy if not managed. In heavy clay that stays wet after a rain, it may rot out over winter.
